SPECIFICATION forming part of Letters Patent N o. 534,428, datedFebruary 19, 1 895. Application filed February 1893- Serial No. 460,551.(No model.)

To a/ZZ whom, it may concern:

Be it known that I, PHINEAS DEAN, a citizen of the United States ofAmerica, residing at Harper, in the county of Harper and State ofKansas, have invented certain new and use.- ful Improvements in Pumps,of -which the fol.- lowing is a specification, reference being hadtherein tothe accompanying drawings, and to the letters and figures ofreference thereon, forming a part of this speciication, in which- Figurel, is a side elevation of the pump, and a sectional elevation of awellinto which the pump is placed; Fig. 2, a detailed section of the upperportion of the pump stock and head, and a side view of a correspondingportion of the rotatable stem of the pump; Fig. 3, a longitudinalsectional View of the upper and lower end portions of the pump stem, anda side view of the point and actuating shank of the st em; Fig. 4, abottom end view of saidV stem; Fig. 5, a cross-sectional view of thepump stem represented as provided with four water passages; Fig. 6, atop end view of the pump stern, and a cross-section of the pump head online 1-1, ofFig.' 2; Fig. 7, a detailed side view of sections of thepump stem and of a screw coupler for connecting the sections; Fig. 8, adetailed side view of the lower end portion of the pump stem having aportion of one water passage covering bands broken' away to show thevalve seat and chamber of said passage, and Figs. 9, 10, and'lll, aredetailed views of onevalve seat of the pump stem. f

This invention relates to-certain improvements in rotary pumps, andconsists essentially in a rotatable stem constructed with spiral waterpassages which is submerged, in a well, at its lower end portion, andadapted to be rapidly rotated and take water into the lower portion ofthe spiral passages, and by reason of the rotary action, force the watern p the inelines of the spiral passages and discharge it at the upperend of the said passages, which improvements are fully set forth andexplained in the following specification and pointed out inthe claims.

Referring to the drawings l represents the pump stock, which iscylindrical in form and screw-threaded and turned into, or otherwisesuitably stepped into a base 2.

3 represents the `pump stock head, and is screw-threaded to correspondwith screwthreads of the upper end of stock l, and'is turned upon saidstock tothe position shown, and is provided in one side with a spout S,in its crown with a central opening at one side from its center with anupright arm 7 bearing at its end a horizontal shaft bearing 8, and witha stud 9 extending at one side in verticallinewith bearing 8.

4 represents the pump stem, which is, at its exterior, cylindrical inform, and is preferably made of cast metal, and provided with spiralwater passages P formed in its walls within the cylindrical planethereof, as shown, which passages are made with covering bands c, placedin seats as represented. The said covering bands'are held seated bymeans of a suitable cement, and may also be held at the ends thereofby'm'eans of screws, as shown at e a Fig. 8. The said stem, when cast,is hollow, as represented, and each end thereof is made so the openingthereinl will be circular and is at such openings screw-threaded, and atthe bottom end has turned therein a supporting, or pivot, point 16, andat the top end it has turned therein a shank- 5. About the upper end ofstem 4 is placed acollar D, shown as being xed in-to position by meansof a cross-pin o, and placed about under said collar is a packing washerw. f

In the lower end portion of each water passage P is an enlarged chamber,or section of the passage, P and arranged in each such chamber is avalve seat E, set in a recess made for that purpose; and each said seatis provided with a ball valve B (see Fig. 8) so arranged that by van upflow of ,water the ball is unseated and permits the water to pass, butcloses against the down passage of water. The passagesPopen both at thebottom and top ends of thestern 4 and by reason of their spiral form andopen lower end will, when stepped in water and rotated, cause the waterto enter into the said passages and by rapidly ro-v tating the stem suchaction will. cause the water to iiow up the spiralv inclines of thepassages and be discharged at the top end of the stem. As a means ofassisting in supplying the passages P with water, when in service, Ihave provided a series of ports R (see Figs. 1 and 3), which lead fromthe side of stem 4 to withinfthe passages P, below the valve IOO seats,which, when the stem is rotated will take in water and lead it to thepassages l? and not while in saidports be subjected to the rotary actionin such manner as to prevent such lead, by reason of the laterallycurved form of said ports as indicated by dotted lines in Fig. 4.

In service the stem 4 is placed in a well, as represented in Fig. 1, andrests with its pivotal point 1G stepped in asocket of a support 18placed in the Well, in such manner that the lower end of the stem issubmerged. The upper end portion of the stemis placed within the stock,l, with the washer packing@ seated upon the stock l and with the collarD bearing lightly upon washer t. The stock head is then placed inposition on stock l which brings the stem shank 5 extending through thecrown opening of said head, as shown in Fig. 2.

As a means of operating the stem 4 I have provided a bevel pinion 10,which is provided with a square opening through its hub and sleeved uponthe square shank 6 of shank 5. In bearing 8 I have placeda short shaftbearing, at one end, a bevel wheel 1l, arranged in mesh with pinion 10,and at its opposite end a spur pinion 12,and on stud 9 I have placed aspurwneel 13 which meshes with pinion l2, and is provided with a handcrank handle 14, and by grasping the handle 14 and turning wheel 13 theproper rotary movement is, through the agency of gears 12-ll and 10,given the pump stem 4 causing it to take in water at its lower end, andby the centrifugal action,causcs the water to flow upthe passages l) andbe discharged within the pump head 3, from whence it flows out throughspout S, and during the action of pumping water is prevented fromflowing down about the stem into stock 1 by the collar D and packingwasher W.

I have represented in the principal drawings the stem 4 as provided withtwo water passages, and in Fig. 5, as provided with four such passages;but the number of said passages is not material, as any suitable numberof them may be used and the pattern of the stem may be altered and notaffect the principle of this invention; also in Fig. l, I haverepresented, by cross-lines, the stem 4 as made up of sections, and inFig. 7, I haveshown the meeting end of two sections, in the act of insaid passages when the rotary action of the stem 4 ceases, and thus,after a pump has been brought into service, at each stop, or cessation,of action the water is retained in the passages, so that when againstarted into action the water is immediately in readiness to bedischarged, and therefore does not have to be drawn` from the bottom ateach such commencement.

The pivotal support 18, shown in Fig. l, upon which stem 4 is stepped,is shownas a plate having perforations 20, which is fixed upon a hollowscreen point 19, so that the water from the well bottom first must passthrough said screen and plate perfor-ations before reaching the stem 4;but the form of said support is not essential and may be varied tosutcircumstances.

Having thus described my invention, what I claim as new and useful, anddesire to secure by Letters Patent, is as follows:

1. In the herein described pump, the rotatable stem provided with thespiral water passages, with the valves placed in said passages, and withthe side ports leading to said passages from the stem side,substantially as and for the purpose specified. y

2. In the pump described, the combination with a pivotal support, of thestem 4 provided with the spiral water passages, and with the i point 1Gand shank 5-6; the stock 1 and base thereof; the head 3 of said stockprovided with the spout the crown opening and the supported bearing 8`and stud 9; the collar and packing washer placed about the pump stemwithin the stock head,and of the gears 10-11-12 and 13, for operatingsaid stem, in the manner substantially as and for the purpose set forth.
